While HPV infection is the leading cause of cervical cancer, in reality it is very rare for HPV infection to progress to cancer with proper treatment. 60 to 80 % of CIN 1 dysplasias resolve on their own, and only about 1% of cases progress to invasive cervical cancer.

HPV CLEARANCE INFORMATION

HPV Clearance rates...

Center for Disease Control:
"Studies have shown that 70% of new HPV infections clear within one year, as many as 91% clear within two years. The median duration of new infections is typically eight months. HPV-16 is more likely to persist than other HPV types; however most HPV-16 infections become undetecable within two years. The gradual development of an effective immune response is thought to be the likely mechanism for HPV DNA clearance."

Planned Parenthood:
"The average duration of HPV infection was eight months. Repeated HPV DNA testing showed that seventy percent of the women cleared their HPV infections within one year through the natural immune process, and only nine percent continued to be infected after two years. Another study conducted in Sweden supported these findings, with a five-year clearance rate of 92 percent"

What Does HPV "Clearance" Mean?

Association of Reproductive Health Professionals (ARHP):
"Most people (up to 90%) who test positive for HPV with very sensitive tests for HPV (polymerase chain reaction [PCR] and Hybrid Capture® II) will become HPV negative on the same tests within 6-24 months from first testing positive. This is due to an effective immune response to HPV."

Indiana University
"Since HPV is a virus, there is no cure. However, new studies indicate that approximately 70-90% of people with HPV may clear the virus from the body within two years of infection."

How does the body clear HPV?

American Social Health Association (ASHA):
"In almost all cases, the immune system will keep the HPV virus (including the cancer-related HPV types) under control or get rid of it completely."
